    So, just how does Addison stay so fit, anyway? Her cardio doesn't just come from doing TikTok dances. Addison is also a big fan of Pilates, and she's been spotted taking classes with Hailey Bieber by the Daily Mail. Her other go-to is the Dogpound gym, where Addison crushes intense workouts, like this one:

    Those battle ropes and bear plank kickbacks didn't even know what hit them.

    Even Kourtney comes to Addison for workout advice—the pair once sweated it out while doing a booty workout together in a YouTube video, according to E! News. "I've done this butt workout so many times because it literally burns so bad but it's so good," Addison said in the vid.

    The routine features six minutes of killer exercises like donkey kicks, fire hydrants, and fire hydrant extensions. "I have such a good butt workout that I wanna see how yours is and then I feel like we should do other day where I show you mine," Kourtney commented while following Addison's moves.

    Tbh? I'd watch it! After all, besties who sweat together, stay together.
